  • Now that you have a plan and materials ready, it's time to bring your robot to life — on paper or with simple materials! This is where your idea becomes a model you can touch, test, and improve.

    • 📐 Step-by-Step Guide to Building Your Prototype

      1. Draw Your Robot’s Shape: Use a pencil to sketch the robot body on thick paper or cardboard. Think of boxes, circles, arms, and wheels.
      2. Cut and Fold: Cut out the shapes and fold where needed to give 3D form. Glue or tape pieces to create a standing model.
      3. Add Movable Parts: Use paper fasteners, straws, or pins to make simple joints for arms or legs that can move.
      4. Label Key Parts: Write on the robot where sensors, motors, or lights will be placed in a real version. This helps others understand your design.

      🧃 Use What You Have at Home

      • Cardboard boxes for body
      • Paper straws or toothpicks for joints
      • Bottle caps for wheels
      • Glue, tape, markers, and scissors

    • 🎒 Real-Life Connection

      Prototyping like this is how real engineers and designers test their ideas quickly without spending too much. Even companies like ISRO and NASA use simple materials first before jumping to expensive builds.

      💡 Fun Challenge

      Make a paper robot that can do one of the following:

      • Wave its hand
      • Roll forward using a push
      • Stand upright on its own

      Take a photo and explain to a friend or family member how your robot would work in real life. That’s how real innovation starts — by sharing!
